Craig has a number of programs that are based around socketcan and should, in theory, work with the slcan interface possible with M2RET. Examples: ICSim, UDSim, CaringCaribou. I havenβt tested them with an M2 but I think we ought to do so as they provide some useful things we would otherwise lack. I know that CaringCaribou didnβt work well when I tried it with a GVRET device a few years ago but the situation might be different now.
